Drawback
RAID 1 treats the entire array as a single drive with the storage
capacity of the smallest physical drive in the array. So if you
have two drives (300 GB and 250 GB) in a RAID 1 array, your
computer only recognizes a single drive with 250 GB total
capacity.

RAID for both: performance and security
RAID 5 uses striping (at the block level) with on-the-fly error
correction across all drives. Because of this error correction,
small file read/write errors can be quickly and automatically
fixed without a significant drop in system performance.
RAID 5 offers good performance and data redundancy. This
array preserves your files if a drive fails.
RAID 5 stripes both data and parity information across
multiple drives. Striping across drives improves overall
performance, and the parity information provides data
protection. Because of the error-correction capabilities, if a
drive fails, the data can be quickly and automatically fixed.

RAID 10 (also called RAID 1+0 or RAID 1&0) contains sets of
RAID 1 mirrors acting as drives within a RAID 0 striping array.
With this setup, the array could survive one drive failure in
each mirror array.
